RFID-Tags for Anti-counterfeiting

RFID-tags are becoming very popular tools for identification of products. As they have a small microchip on board, they offer functionality that can be used for security purposes. This chip functionality makes it possible to verify the authenticity of a product and hence to detect and prevent counterfeiting. In order to be successful for these security purposes too, RFID-tags have to be resista...

Anti-counterfeiting Using Memory Spots

We propose a new hardware and software solution for anticounterfeiting that puts product authentication directly into the hands of end-users, enabling them to be confident of the authenticity of a product regardless of the integrity of the distribution chain. This is made possible by a new type of tamper-resistant hardware chip, called “memory spot”, which has a unique combination of small size...

Designing lanthanide-doped nanocrystals with both up- and down-conversion luminescence for anti-counterfeiting.

The widespread forgery in all kinds of paper documents and certificates has become a real threat to society. Traditional fluorescent anti-counterfeiting materials generally exhibit unicolor display and suffer greatly from substitution, thus leading to a poor anti-counterfeiting effect. In this work, unseen but significant enhanced blue down-conversion emission from oleic acid-stabilized lanthan...

RFID Anti-Counterfeiting for Retailing Systems

Counterfeiting is one of the most serious problems in the consumer market. One promising approach for anti-counterfeiting is to attach a low-cost Radio-frequency Identification (RFID) tag to the product authentication. In this paper, we propose an RFID system for detecting counterfeiting products. This RFID system consists of the tag authentication protocol and the database correction protocol....
